For this question you need to attach a file in Excel with your calculations. What do we call the cost of capital at which the two projects have the same NPV? Find this cost of capital for projects X and Y below Project X: CF=- $3,500; CF2 = $900; CF 2 = $1,000; CF3 = $1,200; CF4 = $750; CF5 = $120. Project Y: CF. --$3,000; CF2 = $700; CF2 = $900, CFz= $1,000; CF4 = $700
